Summary:PROBLEM TO BE SOLVED: To provide a piezoelectric device employing a combination of eutectic metal and resin material as sealing material for a through-hole, and provide a sealing method for the piezoelectric device. SOLUTION: The piezoelectric device (100) includes a piezoelectric vibration piece (30) inserted between a lid (10) and a base (40). A plurality of through-holes (41, 43) penetrating the base (40) are formed at the base (40) to be used for conduction of the piezoelectric device to outside (45, 46). Each of the through-holes is sealed by a combination of eutectic metal (18) and resin material (19). COPYRIGHT: (C)2010,JPO&INPIT
